424 | or system utility to be loaded and invoked. When the DXE Core has dispatched\r | |
425 | all the drivers on the dispatch queue, this function is called. This\r | |

427 | the selected operating system or system utility. During this process,\r | |
428 | additional firmware volumes may be discovered that may contain addition DXE\r | |
429 | drivers that can be dispatched by the DXE Core. If a boot device cannot be\r | |
430 | fully connected, this function calls the DXE Service Dispatch() to allow the\r | |
431 | DXE drivers from any newly discovered firmware volumes to be dispatched.\r | |
